Inter-layer bias effect on time-reversal symmetry breaking in twisted bilayer cuprates
Mathieu Bélanger, David Sénéchal
We study a one-band Hubbard model of twisted bilayer cuprates with a twist angle of . By introducing an inter-layer bias, we simulate heterobilayers of different dopin…
CDMFT+HFD : an extension of dynamical mean field theory for nonlocal interactions applied to the single band extended Hubbard model
Sarbajaya Kundu, David Sénéchal
We examine the phase diagram of the extended Hubbard model on a square lattice, for both attractive and repulsive nearest-neighbor interactions, using CDMFT+HFD, a combination of C…
Topological analog of the magnetic bit within the Su-Schrieffer-Heeger-Holstein model
Xinyuan Xu, David Sénéchal, Ion Garate
In magnetic memories, the state of a ferromagnet is encoded in the orientation of its magnetization. The energy of the system is minimized when the magnetization is parallel or ant…
Dynamical Variational Monte Carlo as a quantum impurity solver: Application to Cluster Dynamical Mean-Field Theory
P. Rosenberg, D. Sénéchal, A. -M. S. Tremblay +1
Two of the primary sources of error in the Cluster dynamical mean-field theory (CDMFT) technique arise from the use of finite size clusters and finite size baths, which makes the d…
Doping dependence of chiral superconductivity in near twisted bilayer cuprates
Mathieu Bélanger, David Sénéchal
We study a one-band Hubbard model for a twisted cuprate bilayer with a twist angle of 43.6 and a moire cell containing 58 sites. We use the variational cluster approximatio…
Pyqcm: An open-source Python library for quantum cluster methods
Théo N. Dionne, Alexandre Foley, Moïse Rousseau +1
Pyqcm is a Python/C++ library that implements a few quantum cluster methods with an exact diagonalization impurity solver. Quantum cluster methods are used in the study of strongly…
